4 Claims.

lviy invention has reference to a closet connection and test capmechanism, and is more specially designed for use with a multiplearrangement 01 all-hung closet carriers or chairs. A row 5 or series ofthese chairs is set just within a wall and connections made with a drainsystem for waste er, which system is also back of the wall. .N bowls ortoilets are supported from said against the outer face of the wall,

19 and coupled up with said connections so that the w te water will passthrough the same into the drain pipes.

er the plumbing system has been roughed in,

before the bowls are installed, it is usual to re a test of the system,to determine if it is non-lealrable. In order to do this it is necessaryto close the openings into the connections by m s expansion test plugsor similar means,

1e chief purpose of the present invention is to 1 ovide a simple andinexpensive capping apparatus by means of which the openings may betemporarily and tightly closed, and the parts of whi h can be quicklyremoved to make way for the installation of the bowls after the test hasbeen completed. The apparatus can be used any number of times withplumbing systems as they are being installed.

In mounting a series of bowls in alignment against a wall there isdanger of one or more of the bowls being improperly positioned, byreason of inequalities or other inaccuracies in the face of the wall,and in the present invention this is sought to be overcome by providingconnections which will be capable of adjustment in the chairs,

so that the bowls can be set squarely against the wall, and in alignmentwith each other. This is accomplished by making a threaded connectionbetween the end of the chair connection and chair.

In connection therewith is provided a means for preventing leakagebetween the connection and chair, and means for locking the connectionfrom movement, after it has been adjusted.

Another purpose of the invention is the provision of means forsupporting the test caps so that they are capable of being adjusted withreference to the chairs, so that the same may be made to conform to theadjustment of the chair connection. 7

The above named, and other features and advantages of the invention willmore fully appear from the following specification, reference being 55had to the accompanying drawing, wherein;

Fig. 1 shows a closet chair in front elevation, with a test-cappositioned thereon.

Fig. 2 is a plan View thereof.

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 2.

The reference number 1 indicates the vertical plate of a closet chair orsupport, connected with a footing 2 by means of bolts 3 passing throughan upright 4 of the footing, and through slots 5 in said plate. By thismeans said plate may be adjusted vertically to adapt the same forconnection with the waste pipe system. This part of the apparatus is notnovel in itself. In the plate 1 is an opening 6, provided at its innerend with a collar 7, threaded to receive one end of a coupling '7 forconnectionwith a pipe system not shown in the drawing. Said collar isprojected outwardly into a ring 8, internally threaded to receive oneend of a connection 9, provided throughout its length with a screwthread 10. On i the outer end of the connection 9 is a circular seat 11,with which is connected 2. coupling member of a bowl, when the bowl isin place. Near the inner end of the connection 9 is a lock-nut or ring12, threaded to turn thereon, and between 86 said ring and the end ofthe ring 8 is a gasket 13. of a material suited to prevent the passageof water outwardly between the ring 8 and connection 9. By a propermovement of the lock-ring the gasket is not only forced against the ring8 so as to form a tight packing, but the connection 9 is held fromrotating. When properly positioned the inner edge of the seat 11 is inline with the face of the wall,indicated in broken lines at 14.

When the system is to be tested each of the 96 connections 10 is closedat its outer end by means of circular caps as shown at 15, each providedwith a dome 16, with radial wings 17, ending in threaded eyes 18, inwhich are threaded bolts 19, on the outer ends of which are nuts 20. Theinner ends of said bolts are received in threaded openings 21 in theplate 1, and by turning said bolts the cap 15 can be moved inwardly oroutwardly to cause the same to conform to the position of the connection9. Between. the cap 15 and seat 11 100 is a packing ring 22, formed ofcomposition or other suitable material. Said ring also forms a seat forthe end of the bowl coupling, when the bowl is installed.

After the test of the system has been made the 103 caps 15 are detachedand the bowls secured in place in the usual manner, by means of threadedbolts 23, the ends of which engage similarly threaded openings 2% in theplate 1. A coupling I member projecting rearwardly from the bowl takesthe place of the test cup in the seat 11, and is held in tightengagement with the packing ring 22 by means of the bolts 23.

The center of the test-cap is provided with a threaded opening 25, toreceive a plug 26, fitted with a wrench-hold 27. By removing the plug aconnection can be made through the opening for introducing liquid orfluid under compression into the system for the purpose of making tests.

What I claim, and desire to secure by Letters Patent, is;-

l. A device of the class described, comprising a closet chair formed ofa main plate and footing therefor, a coupling in the main plate andintegral therewith, provided in both of its ends with internal threads,an externally threaded connection engageable with the outer end of saidcoupling, and provided at its outer end with a female coupling, atest-cap held in said female coupling and provided with a pair of wingshaving bolt openings, and bolts in saidopenings having a tappedengagement with said main plate and adjustable to conform with theposition of said test-cap with relation to the plate.

2. A device of the class described, comprising a closet chair formed ofa main plate and looting therefor, a coupling passing through said mainplate and integral therewith, both ends of said coupling being providedwith independent internal threads, an externally threaded connection inengagement with the outer end of said coupling, for adjustablepositioning therein, and provided with a coupling socket at its outerend, adapted to receive a pipe end, a test-cap seated in said socket,having a domeshaped portion provided with a tapped central opening, aplug held removably in said opening, wings integral with said test-capprovided with bolt openings, and bolts in said openings having a tappedconnection with said chair and adaptable to the position of saidtest-cap with relation to said chair, the testcap being removable topermit of the use of another part with said socket.

3. A device of the class described, comprising a closet chair consistingof a main plate and footing therefor, a coupling in said plate havinginternally tapped ends, an externally threaded connection in engagementwith the outer end of said coupling, and provided with a coupling socketat its outer end, a lock-ring on said connection, engageable with theend of said coupling, a test-cap seated in said socket provided withwings having bolt openings, and oolts in said openings having a tappedengagement with said plate, and adapted to hold said test-cap inadjusted positions conforming to the position of said connection.

4. A device of the class described, comprising a closet chair consistingof a main plate and footing therefor, a coupling integral with saidplate having internal screw threads in both of its ends, an externallythreaded connection in engagement with the outer end of said coupling,and adjustable axially therein, a coupling member on the outer end ofsaid connection, a test-cap seated in said coupling member and providedwith bolt connections, bolts held in said connections and having tappedconnections with said main plate, and auxiliary bolts also tapped insaid main plate for. alternative use with parts other than saidtest-cap.
